To all whom it may concern:

Be it known that I, WILLIAM C. LANG, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Mold-Maklng Machines, of which the following is a specification.

My invention relates to improvements 1n mold making machines, and is particularly designed and adapted for receivlng, supporting and handling of the respective flasksections together with the head and base boards and the pattern-plate and the filling or compressing or ramming of the molding sand in the act of formlng a complete mold.

fhe primary object of the invention 18 to provide a generally improved machine of this class of exceedingly simple, cheap, and elficient construction in which the various parts may be readily adjusted to meet the varying demands of actual service.

A further object is to facilitate the handling of the various parts necessary to form a complete mold as well as provide a machine of this class adapted to receive and properly handle pattern-plates and flasksections of varying thicknesses employed in making molds of varying forms.

A still further object is to provide improved means for holding the flask-sections and other parts in proper superposed relation to each other while the flask contents are being compressed as well as providing improved means for completely and uniformly compressing the cope and drag sections of the complete mold.

A still further object is the provision of improved means for engaging, supporting and separating the different mold forming parts during and upon the completion of the compressing operation.

A still further object is the provision of an improved auxiliary or supplementary cope flask-section superposed above and cooperating with the main upper or cope flasksection and adapted to facilitate the striking-ofi or leveling of the main cope section when the head is removed.

With the above mentioned, and other ends in view, the invention consists in the novel construction, arrangement, and combination of parts, hereinafter described, illustrated in one of its embodiments in the accompanying drawings, and particularly pointed out in the appended claims.

Referring to the drawings, forming a part of this specification, Figure l, is a top plan view of the improved mold making machine, the pattern-plate being attached and the vertically movable mold compressing table being removed for the purpose of clearer illustration of the parts.

Similar numerals of reference designate like parts throughout all the figures of the drawings; i

The improved machine comprises a suitable frame, in the present instance, comprising a base section 1, mounted on suitable wheels 2, and provided with vertical bearing posts 8, connected to and supporting asecond horizontallyextending section 4:, said second section including extensions 4?, extending beyond the posts or bearing columns 8. The extensions 4*, are braced or supported by means of brace members 1*, and are adapted to normally support a pivoted head carrier 5, on one side and a suitable pattern-plate 6, on the other.

Thebase-section 1, may be connected by means of channel members 1", and the upper section 4, may be similarly connected and braced by means of channel members at".

The head carrier 5, when in its inverted position may be supported throughout its central portion by means of a transverse member t", and the pattern-plate 6, may be similarly supported by means of a series of brackets 7, carried upon a transverse bar 8, the latter being'adjustably mounted through the medium of adjusting bolts 8, in slots 8, in the vertical portions of the extension 4;. The head carrier 5, is provided with inclined arms 5 pivotally connected to bearing posts or columns 9, through the medium of pivot bolts 9*, and as a means of adjusting the bearing portions of the arms 5 whereby the head carrier 5, may be adjusted to accommodate flask-sections of varying thickness said bearing posts are mounted in guideways 3 of the posts 3, and are adapted tolbe adjusted through the medium of adjusting bolts 3 mounted in guide slot-s 3,

as shown most clearly in Fig. 2 of the drawings. As a means of counterbalancing the weight of the pivoted head carrier 5, in its respective positions as well as facilitating its movements to and from said positions, counter-balancing coiled springs 10, are pro- Vided, said carrier 5, being adj ustably braced and being adapted to receive and carry a suitable head or board 11. The inclined arms 5 carrying the head carrier 5, are also provided with cam members 5", for automatically actuatingsaid pattern-plate and upper flask engaging and separating devices as hereinafter described.

The pattern-plate 6, is detachably connected to and carried by a pair of hinged pattern carriers 6, said pattern carriers being detachably secured to one edge of the pattern-plate by means of bolts A, or other securing elements, said carriers 6, being hingedly connected to the bearing posts 12, through the medium of bearing pins 6", (see Fig. 14) adapted to have a vertical movement in bearing guide slots 12 of the bearing heads of the posts 12, whereby a limited 'movement of the pattern carriers will be permitted during the mold compressing operation as hereinafter more fully described. The bolts 6 are connected to and are adapted to be rotated by the actuation of the pattern carriers and are provided on one side with guide extensions 6, and at the other with heads (3, connected to links 13, which latter are connected to bearing bolts 14:, mounted in the bearing posts 8, said bearing bolts 14-, carrying latching levers or members 15, terminating in beveled hooked heads 15. By reason of the construction described when the pattern carriers (3, and attached pattern 6, together with the inverted superposed lower fiask-section and baseboard are swung from the position shown in Fig. 2 to the position shown in Fig. 12, the latching levers or members 15, will be swung to the upright positions indicated by dotted lines in Fig. 2 and in full lines in Fig. 4:, and as a means for causing said latch levers to be held inwardly for automatically engaging with the free edge of the head carrier 5, when the latter is swung to the position shown in Fig. 12, said latching or looking members 15, are provided with extensions 15", adapted when swung upwardly to come into ongagement with and compress flat springs 16, as shown most clearly in Figs. 2 and 4: of the drawings, and as a means for permitting said latching or locking members to have a limited free movement on the bearing bolts 14:, the latter are provided with key members 14:, adapted to slide in groove-ways 11, as shown most clearly in Fig. 4 of the drawings, it being apparent that when the beveled heads 15 are engaged by the free edge of the head carrier 5, and moved out of the dotted line position shown in Fig. 2 to the position indicated in full lines in Fig. 4 that the springs 16, will automatically throw the latch members into engagement with the head carrier 5, as shown in Figs. 12 and 13.

The bearing posts 12, are mounted in vertical guidesleeves 17, and are adapted to be adjusted vertically through themedium of adjusting nuts 12, whereby the pattern carriers 6 may be adjusted toconform to patterns and flask-sections of varying thicknesses.

When it is desired to form a mold, the pattern-plate 6, is first attached to. the hinged carrier 6, and mounted in the position shown in Figs. 1 and 2 of the drawings. The lower flask-section 18, is then mounted in its inverted position upon the patternplate as shown in Fig. 2 of the drawings and filled with molding sand after which the base board or mold bottom 19, is placed thereon. As a means of looking or latching the pattern-plate and superposed inverted lower flask-section and base board in the position just described, a pair of rods 20, are provided said rods terminating at their base portions in elongated guide loops (see Figs. 10 and 13) adapted to slide upon the ends of the bolt extensions 6, and being adapted to have a limited movement thereon through the medium of adjustable bearing clips 21, the latter being secured by means of clamping bolts 21. By adjusting the clamping clips 21, the play of the pivoted portions of the rods 20, may be varied in accordance with the thickness of the pattern-plates and flask-sections. The retaining rods 20, are adapted to be swung outwardly over the base board 19, shown in Fig. 2 and are provided with adjustably mounted clamp members 22 adapted to engage on opposite sides of the lower flask-section as shown and the free ends of the bars or rods 20, are provided with angular extensions carrying adjustably mounted clips 23, provided with a cross bar 24, the latter carrying a pair of counter-balanced latches 25, which latter are adapted to be snapped into engagement with the free edge of the pattern-plate as shown in Fig. 2 for holding the parts as shown in proper relative position preparatory to and during the swinging of the lower flask-section to proper position upon the compressing table 26, as shown in Fig. 12 of the drawings.

The compressing table 26, is mounted on a piston plunger section 27, carried within a cylinder 28, which cylinder 28, is adapted to be supplied with a suitable operating fluid such as air or the like, through the medium of a conduit pipe 29. The upper flasksection 30, may then be superposed above the pattern-plate 6, and filled with sand after which my improved auxiliary or supplementary upper or cope forming flask-section may be properly mounted and filled with sand and struck off and the head board 11, placed in position together with the head carrier 5, the latching levers 15, automatically engaging with the free edge of said carrier 5, as shown in Fig. 12 and as hereinbefore explained.

As a means of engaging and supporting the upper flask-section 30, in its proper position as shown in Fig. 12, as well as for engaging and separating said section, together with the pattern-plate as shown in Fig. 13, when the pressure of the operating fluid is released from the cylinder carrying the compressing table, vertically extending supporting bars 31, are provided, said bars being mounted in supporting plates 32, slidably mounted in guideways 33, and as a means for actuating or drawing said supporting bars 31, toward each other and holding the same in such position when the pivoted head carrier 5, is in the position shown in Figs. 12 and 13, a pair of levers 34, are pivotally mounted at each side of the frame so that the upper or free ends thereof will be engaged and actuated by the cam members 5 of the arms 5, of the head carrier as shown, said levers being connected at their lower ends to links 34, and spring links 35, connected to crank arms 36, the latter being carried upon crank shafts 37. The crank shafts 37, are provided with links 38, connected to'the slides or plates 32, on one side, and the opposite portions of the shaft 37, are provided with crankarms 39, connected to links 40, the latter being connected to the opposite pairs of slide plates 32. The bars 31, are provided with adjustable brackets 31*, adapted to engage with the flanged projections 30', of the upper flask-section and the projections 6 of the pattern-plates.

As a means of moving the supporting bars 31, outwardly whereby the adjusting clips 31*, are moved to clear the flanged projections 30, and 6 for the insertion and removal of the flask-sections above the com pressing table, the base portions of the pattern carriers are provided with cam heads 6, to contact with a lever 41, connected to a link member 42, the link 42, being connected to a crank arm 43, on the crank shafts 37, so that when the pattern-plate 6, is swung to the position shown in Fig. 2 the cam heads 6 have contacted with and moved the levers 41, inwardly and holding the supporting bars 31, and brackets 31 in their outer position as indicated in Figs. 1 and 2 of the drawings.
